The largest saving comes before the first declaration: choosing the eco-organisme and the product lines. The four approved schemes publish different rates for the same product. For example, clay bricks cost €1.35 a tonne at Ecominéro and €2.54 at Valobat, while structural steel costs €1.00 a tonne at Valobat and €20.00 at Valdelia. Correct classification, scope and the right declaration regime do the rest. None of this means declaring less than you sell: quantities are what you placed on the market.Sources (8)Ministère de la Transition éMinistère de la Transition écologique — Produits et matériaux de construction du secteur du bâtiment (PMCB), page mise à jour le 24 novembre 2025

Six legal levers, with figures
- The scheme. Bricks: Ecominéro €1.35 vs Valobat €2.54 a tonne. Steel: Valobat €1.00 vs Ecomaison €2.00 vs Valdelia €20.00. See the 26-product comparison. Sources (2)ValobatValobat — barèmes PMCBEcominéroEcominéro — Barème à compter du 1er août 2026
- The line. CEM II Portland-composite cement has its own Ecominéro line (€9.23 vs €10.26). Powdered adhesives over 25 kg cost €4.40 a tonne at Valobat against €110 for pastes. Over-95%-metal lines are half the mixed-metal rate at Valdelia. Sources (2)ValobatValobat — barèmes PMCBEcominéroEcominéro — Barème à compter du 1er août 2026
- The scope. Products used only during the works, products for civil engineering outside building plots, and products exported out of France are not declared. Keep the evidence.
- The regime. Under €2M turnover or 100 tonnes, Valobat's simplified regime may cost less than the general one (with a €90 minimum). See declarations. Sources (2)ValobatValobat — Le régime de déclarations simplifiées pour l'année 2027ValobatValobat — barèmes PMCB
- One contract or two. With both categories, one Valobat contract can cost less in time than Ecominéro plus a category 2 scheme, even where a rate is higher.

- Join yourself. When a foreign manufacturer joins, its French importers no longer pay, so the eco-contribution is paid once, on lines the manufacturer controls. See importer or manufacturer.
What does not count as saving
Declaring lower weights or quantities than you sold, or moving products to a cheaper line they do not fit. Both expose you to corrections and penalties. We declare what you sold, on the lines that fit it.
Our own data
The rates on this page come from the same tables as our free calculator, which includes all of Valobat's published PMCB lines, and from the open market data we maintain. ADEME
Price
Our fee. Construction products are quoted separately, because the work depends on the eco-organisme (Ecominéro takes monthly declarations, Valobat one a year) and on your tonnage. Plus Pro starts at €990 a year for up to 10 tonnes; above that we send a written quote. Setup is €0. Eco-contributions go to the eco-organisme at its published rate, with 0% markup. See pricing or the construction products service.
Frequently asked questions
Is changing eco-organisme allowed?
Yes, under the terms of the member contract, usually at the end of a year.
Does eco-design reduce the contribution?
Some lines reward recycled content or bio-based materials (Ecominéro has recycled-content and recycled-aggregate lines, Valobat bio-based lines). We check what your products qualify for. ADEME
Can a representative guarantee a saving?
No one can promise an amount before seeing your product list. We price it at each scheme and show you the figures before you decide.
